  or key into inputfield:
  - defaultvectors (DX,DY, DZ, DIX, DIX, oder DIZ) -
  - oder select vector in browser
  - or define plane (its normalvektor will be used)



<p><a name="F4"><h3>move points of curve along vector with fixed length</h3></A></p>
  "vector"  like above
  "length"  key vectorlength




<p><a name='F10'><h3>modify</h3></A></p>
